MACHINE FOR INSPECTING ANID'C'UTTIHG FABRICS.

Application filed April 28,

T 0 all whom it may concern:

Be it known that I, AMUEL KisLiivrrz, a citizen of the United States, and resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in Machines for In specting and Cutting Fabrics, of which the following is a specification.

This invention is intended to provide a simple and effective machine for the inspection and cutting up of fabrics into short lengths and is particularly advantageous in connection with the inspection of long strips of paper upon which .are placed the figures or legends forming de'calcomania or transfer stamps for the marking of fabrics in a well known manner. 7

To this end the invention consists broadly speaking in a rotary drum made in relatively adjustable sections provided with parallel adjustable guide bars arranged on the periphery of the drum to form guides for the cutting knife, the same being rctatably controlled-as will be explained. This and vother features characterizing the invention will be particularly described in this specification and will be defined in the claims hereto annexed.

In the accompanying drawings 1 have illustrated a simple form and arrangement of mechanism embodying the principles of this invention, in which- Figure 1 is a plan view of the assembled machine. 5 t

Figure 2 is a side elevation thereof;

Figure 3 is a detail in plan view, of the setting scale. I v j Figure 4 is a detail in cross sect-ion showing the drum head, taken in line 4 of Figure 2.

Figure 5 is a detail in section on plane 55 of Figure 2. I v

Figure 6 is a front elevation showing the detail of the strip anchoring plate.

The machine shown in the drawings ,is particularly intended for use in connection with the inspection of cutting up of dccalcomania or transfer stamps in which the individual stamps or figures are imprinted on long strips of thin paper, a short interval-or "blank space being left between each successive group of the stamped figures to enable the strips to be out into short lengthsfor use.

p In the practice of this invention according Specification of Letters Patent Patented llfay 2, 1922. 1920. Serial No. 377,293.

to the form illustrated in the drawings I provide a suitable frame work 1 having at one end notched uprights 2 to receive the journals of the roll 30 which carry the long .roll or strip of paper bearing the transfer headsecitions 8 each of which is provided with parallel cleats 9 separated by a space corresponding to the width of the arms 5 of I the spider so that eaohsection or half of the drum is slidable upon the spider arm 5 toward vand away from the other in order to diminish or increase the circumferential distanceiaroun'd the drum which adjustnient. is

intended for the purpose of bringing the blank: or unprinted portions of the strip in registry" one .above the other as the strip is 1 'wound around the circumference of the re- VOlVlIlg drum. Each of the spider arms 5 is provided witha longitudinal slot through which is passeda headed bolt 10 passing through an aperture in the head of the drum aligned with said slot having at its outer end a winged clamping nut 11 so that the drum head 8 willbe clamped firmly to the spider arms 5 in their various positions of adjustment. I

To facilitate proper and accurate adjustment of the vdrum for differently spaced -strips a graduated scale 7 is placed onthe spider arm 5 adjacent to the inside edges of the head 8 so as to indicate the exact separa tion of said heads from which the proper adjustment may be determined according to the lengths of the printed portions of the P r ip 1 a t The peripheryofthe drum consists of a circumferential series of parallel slats or bars 18/ At intervals around the drum a number of these bars are made adjustable in a circumferential direction so that two adjacentba'rsmay be properly set to form a guide for the cutting knife which is passed between' then lengthwise of the drum to sever simultaneously the numerous layers of paperthat have been wound upon the drum.

This circumferential adjustment of the bars 18 may be effected in any suitable manlocated at points where the unprinted portions of the stamp strip are located in the winding operation, may be adjusted to provide the right width of slot for receiving the blade of the cutting knife which is drawn through the slot between two adjacent bars to sever the strip into the short lengths.

In order to hold the free ends of the severed pieces until the operator is ready to remove them 1 provide clamping members 31 which consist of spring fingers secured by set screws to the outer faces of the appropriate slats or bars 18 to overlap the wrapped long strip of paper on either side of the severing me. V

The drum is rotated by suitable belt connections running from the driving pulleys 23 on the shaft a to and around pulley 22 which is driven directly from a variable speed electric motor 19 whose speed is con trolled by the rheostat 20 whose .movable arm is connected with a foot treadle 21. This variable speed enables the operator to inspect the strip as it is being wound on the drum with more or less care as may be needed and permits the machine to be entirely stopped at will.

The drum ma T be made in any convenient number of sections although in this case I have shown but two sections each of whose heads are substantially semi circular and which are united by cross bars 12.

To fasten the first end of the stamp hearing strip a suitable clamping or holding device should be provided. In this case I have shown a clamping plate 13 extending along the inside face of one of the cross bars 12 and provided with notches to receive clamping twenty-five or thirty layers of this transfer stamp strip may be wound on the drum and rangers will be registered with sufficient accuracy to permit simultaneous cutting of all the layers with the aid of the adjustable bars forming the cutting guides for the cutting knife.

l/Vhat I claim is:

1. In a machine for inspecting and cutting fabric, the combination of a rotary drum comprising a plurality of sections adjustable toward and away from each other to vary the circumferential measurement of the drum, knife guiding bars adjustable about the periphery of the drum arranged to form guides for a cutting knife, and an indicating scale extending in the direction of the movement of the drum sections toward and away from each other to indicate the proper adjustments of the sections for use, substantially as described.

2. In a machine for inspection and cutting fabric, the combination of a rotary drum, transverse slats arranged in parallelism:- around the periphery of said drum and be ing adjustable circumferentially of, the drum in order to form adjustable guides for cutting the fabric, said drumbeingldivided 7 into sections adjustable toward and away from the center, and means for rotating said drum at differentspeeds, substantially as described.

V 3. In a machine for inspecting and cutting fabrics, the combination of an expansible winding drum, a peripheral series of adjustable bars mounted on said drum some ofsaid bars being made circumferentially adjustable thereon, means for gripping one end of the fabric, means for temporarily holding the layers of fabric in position for the cutting operation, and driving mechanism for rotating the drum at different speeds, substantially as described.

a. In a machine for inspecting and out tin fabrics, the combination ofa rotary spic er having longitudinally slotted'radial arms, a sectional winding drunrwhose sections comprise parallel end heads and peripheral slots, the end heads being provided with guide cleats engaging the arms of said spider-so as to have adjustable sliding support thereon, clamping means passing through said slots and the heads of the drum sections for adjustably clamping the cylinder sections in proper relationship, knife guiding members comprising transverse peripheral slats adjustable circumferentially of the drum in order to position them for guiding the cutting knife, substantially as described.

5. In a machine of the class described the combination of a rotary spider, a cylindrical drum formed of a plurality of sections adjustable toward and away from each other on saidspider, means for clamping said drum sections in proper position of adjustment, peripheral guide bars mounted on each section and clamping fingers removably supported on the guide bars for holding the wound on layers of fabric against the periphery of the drum after the fabric has been severed, substantially as described.

6. In a machine of the class described, the combination of a rotary spider, a sectional winding cylinder whose sections are adjustably secured to said spider so as to permit variations in the circumference of the cylinder, a clamping plate for gripping the free end of the fabric to be cut, adjustable guide bars arranged on the periphery of said cylinder to form guides for the cutting knife, and clamping fingers arranged to hold that portion of the fabric next to the line of cutting in position against the cy1- inder, substantially as described.

7. In a machine of the class described, the combination of a winding cylinder comprising a plurality of sections adjustable toward and away from each other each section comprising end heads and peripheral bars and having a circumferentially slotted member, fastening means passing through said slots and having engagement with peripheral bars to hold them in proper position of circumferential adjustment to form guides for a cutting knife, substantially as described.

In witness whereof,'I have subscribed the above specification.
